Flexible lithium secondary batteries have received extensive attentions such as portable devices and flexible electronic devices due to their high energy, power density and reducing environmental problems. Many studies have been accomplished for flexible lithium batteries using gel polymer electrolyte which is providing as high conductivity as the liquid electrolyte with improved safety. UV curing method is well known to obtain chemically cross-linked gel electrolytes and it can be converted to our field of interest to obtain very fast and low-cost production. A Gel electrolyte solution was mixed with Poly(ethylene glycol diacrylate), Methyl methacrylate, Poly(ε-Caprolactone) and liquid electrolyte. Flexible UV GPE was prepared using photo radical polymerization by ultraviolet light and were measured their ionic conductivity and electrochemical properties as a function of blend ratio and amount of photo initiator. |
